Well, now that K. Rool is in, Isaac is my undoubted most wanted. Isaac did well on most every poll I've seen about the Ballot (even though people often try to minimize poll results as skewed, but ehh) which is pretty helpful considering how influential the Ballot seems to be with the choices we've gotten. Isaac received my vote for sure, since I didn't really think K. Rool needed an extra boost. I wouldn't be surprised to see a significant overlap of K. Rool and Isaac fans, so I'm hoping we will see the Golden Boy's support be reenergized now that the King is in.
It does feel like revealing an Isaac Assist Trophy alongside Gray Fox would have made a lot of sense, so I'm slightly hopeful now that Isaac has survived when others have not. If the Assist Trophy isn't back, it obviously can only mean one of two things:
1. Nintendo has heard our cries for Golden Sun, and has graciously answered by making Isaac playable in Smash. We will get an awesome reveal trailer, stage, music, and trophies.
2. Nintendo is literally trying to obliterate all evidence of Golden Sun's existence from memory.
So there are only small stakes at play here.
Ok, I'm joking, but there is a little bit of truth to it.
Anyways, I'm happy with what I've seen of the game regardless, but Isaac would be the cherry on top. Let's make it happen!
